IMPROVEMENT IN SEWING-MACHINE TUCKERS.

Specification forming part of Letters Patent No. [63,290, dated May 11,1875; application filed October 2, 1874.

.To all whom it may concern:

Be it known that I, J. H. CLEVELAND, of Buffalo, in the county of Erieand State of New York, have invented certain new and useful Improvementsin Tucker for Sewing- Machines; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, making a part of this specification.

My present invention is intended as an improvement upon the tucker forsewing-machines for which Letters Patent No. 154,646 were granted to meSeptember 1, 187 4; and the nature of my invention consists in combiningwith said tucker a graduated plate, to which the bow is pivoted by meansof a screw or rivet so as to swing thereon, and be folded in smallcompass when not desired for use, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a perspective view of my improved tucker, and Fig. 2 is abottom view of the same.

A represents the curved bow, provided with the adjustable grooved shoeor guide-foot B, and the adjustable gage O, construc ed in the samemanner as described in my former patent above referred to. D representsthe baseplate, which is graduated along its inner edge, as shown in Fig.1, and provided with a slot, a, through which a thumb-screw is to passto fasten it firmly to the bed-plate of the machine. The lower end ofthe bow or arm A is pivoted to the under side of the plate D at theouter end, by means of a screw or rivet, b,

and when in position on the machine the bow A is in contact with a pin,(1, on the under side of the plate, so that the feed of the machine willhave a tendency to hold the bow in proper position.

When the attachment is fastened to the bed-plate of the machine the gagec is directly in front of the needle. By screwing or unscrewing the gagethe operator regulates the size of the tucks according to thegraduatingmarks on the plate D. Likewise by screwing or unscrewing theshoe B the space between the tucks is regulated. After having made thefirst hem or tuck, the hem or tuck so made is placed wrongside up backof the shoe B, and drawn tight up to the groove in said shoe, and underit and the gage c. The fabric is then turned to the left over the gage cand over the how, when the upper and lower parts of the cloth are drawnstraight on the feed of the machine, and the presser-foot let down, whenthey are ready for work.

Vhen the tucker is not in use the plate is turned 011 its pivot withinthe how, so as to take up but little room.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In combination with the bow A, provided with the adjustable shoe B, andadjustable gage O, the graduated plate D, pivoted to the end of the bowA, and provided with slot a and stop d, all substantially as and for thepurposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this26th day of September, 1874.
